The B1 was introduced in 1942, the first example was named Springbok in honour of a visit by Jan Smuts the Prime minister of what was then known as The Union of South Africa.
The first 40 of the class were named after breeds of antelopes and consequently were often referred as the “Antelope class. For further information google LNER B1

The B1 has subsequently proved to be a popular locomotive for miniaturisation, following on from a design by Martin Evans in 1960 published in the
Engineering in Miniature indeed we have 5 members of this club who between them possess an example.

Class 73 locomotive

Class 73 locomotives were ordered as part of the British Railways' 1955 Modernisation Plan.
This included the extension of the Southern Region electrification to various main lines and Class 73 locomotives were intended as mixed-traffic locomotives, hauling parcels, freight and also
passenger trains. They usually travelled on routes that included some non-electrified sections, such as boat trains, and for this purpose were equipped to operate from the 650 or 750 V DC third-rail
or an on-board diesel engine.

Leader

Very few if indeed any people will have seen this locomotive running on the main line.

Often described as the last giant of steam O. Bulleid was instrumental in many innovative designs as Chief |Mechanical Engineer of the Southern Railway and later for a
few years with British Railways Southern Region after nationalisation For those of you interested in this remarkable man's work then the web article http://www.bulleidlocos.org.uk will tell you all you need to know and more.

Sadly, there is no preserved 'Leader'. The prototype and 2 part built locos were cut up when the project was in its infantsy. By not keeping the prototype, future generations have been denied the
opportunity to fully appreciate this radical design. There is cold comfort in the knowledge that all steam was withdrawn from British Rail within 15 years of this prototype's evaluation so if it has
avoided the British Railway's accountants axe then Dr beeching would have had the same effect.

Today there is only this faithfully reproduced miniature built and owned by our clubs chairman that can be seen in operation pulling riding cars for members of the public, something the
revolutionary prototype never achieved.
